[The expression on Horikawa's features as he tilts his head expectantly at Yamato betrays his amusement, finding the question to be pretty endearing for the most part. (He's pretty sure he explained how to do this, but he doesn't mind doing so again.) Reaching over, he plucks the cigarette back away with a mock sigh.]

Really, Yasusada-kun, it's not that hard! Here, like this. [As if to demonstrate he puts it to his own lips, taking a deep breath in, and when he pulls it away again the smoke he exhales comes in a big puff. With an expectant look back to Yamato, he places the cigarette back between his fingers again.] If that's the case though, I'll be sure to look for those kinds of things. It feels nice to be able to relax once in a while.
